Dear Ansys Users,
I am doing a warpage simulation.
I have a bi-layer material. Simulation starts at 150°C, it goes down to 25°C. At 150°C, the material is straight (like a rectangular box). At room temperature (due to different CTE of the materials which constitutes the bimaterial), material...
Hello everybody,
I am creating a model in APDL.
1)I create the geometry
2)I select my element (plane 183 for instance)
3)I save the database.
4)Now, I have prepared a macro where my material models were implemented.
When I click Material Props/Read from File: and then select my material macro...
Hello everybody,
I have a very basic question. After doing my simulation, I am not able to get back my data/see my BC/Results.
I will describe what I am doing step by step. Maybe somebody can tell me what I am skipping.
FIRST STEP
1)I opened the product launcher and type XX as jobname.
2)I...
Hello,
I am trying to simulate bending of a composite.
My compression strengths and tension strengths are different in all directions.
My question is: when I start applying the displacement (or load) during experiment, the contact point is under compression and at this point, my material...
Hello,
I have an orthotropic fiber reinforced CMC. I have designed a T shaped sample in order to see if I can predict material failure under complex loading conditions (since the actual part which is in service is subjected to complex loading conditions). As can be seen from the overall part of...
Hello everybody,
Currently, I am performing some linear orthotropic analysis near a notch (not exactly a notch but a relative one lets say).
I ended up with the stress distribution that you can see from the attached file.
During my bachelor, I remember that I saw this picture/stress...
Hello,
I am trying to simulate bending test however I have problems with boundary conditions. I am applying my force into the area number 2.
As you can see from picture2, I would like to give boundary conditions to the 1st and 2nd region (where my material touches to the steel parts). In ansys...
Hello,
I have a matrix called compliance matrix (6x6) in 3d-stress space.
It looks like:
x y z 0 0 0
x1 y1 z1 0 0 0
x2 y2 z2 0 0 0
0 0 0 a 0 0
0 0 0 0 b 0
0 0 0 0 0 c
I want to make a rotation. I should turn X axis 45° towards y-axis.
My question is, how can I form my 6x6 rotation...
Hello,
I am trying to find an appropriate theory that describes the behavior of our fully-nonlinear composite. There are several options already implemented in ANSYS and I am trying to get something out of them.
So far, I am only trying to simulate tensile and shear cases.
In the upcoming...
Hello,
We are producing composite materials which consist of plies stack on each other at different angles (like 0°/90°, 45°/45°, 15°/75°,30°/60°).
For the 0°/90° case, we have the same tensile strength in X and Y (principle) directions.
I want to estimate the maximum stress that a...
Hello,
I have a cube (a= 10m).
It represents a orhotropic material. I am giving the properties in X,Y,Z direction. and I would like to apply displacement which would be on 45°.
So I thought if I change the axis as 45°, my new X,Y,Z directions will be different so material properties will be...
hi,
i have a mathematical function (please see attachment for the function and graph).
I will specify sigmaB values and taoB.
sigma1 is the values for positive x axis
sigma 2 is the values for negative x acis
tao 12 is the values for +-y axis.
could you please tell me how I can put that...
Hello,
I am trying to simulate simple tensile and shear behavior of a fiber reinforced composite. Tensile behavior can be simulated without any problem. However, I could not simulate shear behavior. I found some materials failure criterias. I am just wondering how I can start implementing this...
Dear all,
I am trying to simulate fiber reinforced CMC(orthotropic) by ANSYS. I am trying to pull a simple cube and try to see whether my cube is behaving according to the data that I give as input at the same time I am using Hill's potential to determine any failure.
I would like to compare...
Hi everyone,
From bachelor years, I have learned that time-step-schemes can be implicit or explicit.
To solve my problem, I have selected DIRECT SOLVER in the STEP options of abaqus (I have a simple problem and a normal simulation takes like 30seconds to finish). I have a total time of 1...
Hello friends,
I am trying to simulate crack propagation with abaqus.
I have a matrix, fiber, and a cohesive section cutting through both of them.
When I run the simulation, I get the following error:
